How to Install GitLab on Ubuntu Server Latest?

GitLab is a web-based Git repository manager that allows collaborative code sharing, continuous integration, and application-defined deployment. It is an open-source platform that makes it easy to manage your Git repositories on your Ubuntu server.

This tutorial will show you how to install GitLab on your Ubuntu server latest version.

Prerequisites:

• Ubuntu server latest version installed
• A domain name or IP address pointing to your server
• A minimum of 2 GB free system memory

Step 1: Install Dependencies

First, we need to install the required dependencies for installing GitLab on Ubuntu. Use the following command to install the required dependencies:

sudo apt-get install -y curl openssh-server ca-certificates tzdata perl

Step 2: Install and Configure PostgresSQL

Next, we need to install PostgresSQL to store GitLab data. Use the following command to install PostgresSQL:

sudo apt-get install -y postgresql postgresql-contrib libpq-dev

Once installed, log in to the PostgresSQL server as the Postgres user:

sudo -u postgres psql

Create a new user for GitLab, and grant them access to a new database:

CREATE USER git CREATEDB;
CREATE DATABASE gitlabhq_production OWNER git;
\q

Step 3: Install GitLab

Now it's time to install GitLab. We will use the Omnibus package to install GitLab. Use the following command to download the GitLab package:

curl https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.deb.sh | sudo bash

Install GitLab with the following command:

sudo apt-get install gitlab-ce

Step 4: Configuration

Now, we need to configure GitLab. Open the GitLab configuration file:

sudo nano /etc/gitlab/gitlab.rb

Go to the “External URL” section, and set your server's domain name (or IP address) as the external URL:

external_url 'https://example.com'

Next, change the PostgresSQL adapter to a PostgreSQL database:

gitlab_rails['db_adapter'] = 'postgresql'

Now, is time to configure the database data. Go the "PostgreSQL" settings sections and set the settings like these:

gitlab_rails['db_host'] = '127.0.0.1'
gitlab_rails['db_username'] = 'git'
gitlab_rails['db_password'] = 'your_password_here'
gitlab_rails['db_database'] = 'gitlabhq_production'

Save the changes and close the file.

Step 5: Apply Configuration and Reconfigure GitLab

To apply the changes, run the following command:

sudo gitlab-ctl reconfigure

This command will apply your configuration changes and build your new GitLab environment.

Step 6: Complete GitLab Setup

Open a web browser and access your GitLab installation at your server's URL (or IP address). You should see the GitLab setup page.

Create a new admin user and password, then click the "Create account" button.

Next, create a new project or import an existing one to get started with GitLab.

Conclusion

You have now installed GitLab on your Ubuntu server latest version, and you're ready to go with collaborative code sharing, application-defined deployment, and continuous integration. Keep in mind that GitLab has many features, and it may take some time to get used to all of them.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
